A cluster can change—through reconfiguration or administrative
action—after scha_cluster_open returns the cluster's
handle, in which case the information scha_cluster_get
obtains through the handle could be inaccurate. In cases of reconfiguration
or administrative action on a cluster, the RGM returns the scha_err_seqid error code to scha_cluster_get
to indicate information about the cluster might have changed. This is a non-fatal
error message; the function returns successfully. You can choose to ignore
the message and accept the returned information, or you can close the current
handle and open a new handle to access information about the cluster.

scha_cluster_getlogfacility(3HA)

Returns the number of the system log facility being used as
the cluster log. Uses the returned value with the Solaris syslog(3) function to record events and status messages to the cluster log.
